Today, we’re looking at an intake air temperature sensor that also functions as a mass airflow sensor. If you’re receiving a trouble code related to the intake air temperature sensor, there’s a quick way to test it to ensure it’s working correctly. Let’s dive into the steps to test and troubleshoot this sensor.
Firstly, you need to locate where the sensor is in your vehicle. You can refer to Google image search, vehicle forums, or consider purchasing a repair manual specific to your vehicle for this information.
Once you’ve located the sensor, it’s time to remove it from the vehicle. It’s advisable to disconnect the negative terminal from the battery to prevent any electrical mishaps. Gently remove the sensor and place it on a workbench.
Now, to test the sensor, you’ll need a digital multimeter. Conduct a resistance or ohms test with the multimeter, aiming for a reading between 2 to 2.5 kilo ohms at 70 degrees Fahrenheit, which can vary based on the external temperature. By applying heat to the sensor and observing the change in the reading, you can verify its functionality.
If the sensor provides a reading when heat is applied, it indicates that it’s working correctly. However, if there’s no change in the reading, it’s a sign of a faulty sensor. It’s essential to conduct this test to rule out any issues with the sensor itself before exploring potential wiring or connector problems.
Ensuring that the sensor is in optimal condition can save you from unnecessary expenses and troubleshooting efforts. By following these steps, you can quickly assess the intake air temperature sensor’s functionality and address any related trouble codes effectively.
